Several tests of GR have been demonstrated using the observations of GW
signals by the LIGO-Virgo Collaboration (LVC) [1]}, [2]}, [3]}, [4]}, [5]}, [6]}. Among them are the theory-agnostic parameterized tests of the
inspiral, which check for the agreement of the early
evolutionary (or inspiral) phase of a compact binary coalescence
composed of BHs and/or NSs with the analytic post-Newtonian (PN)
approximation for binaries in GR [7]}, [8]}, [9]}, [10]}, [11]}. Parameterized
GR waveforms have used the LIGO-Virgo observations to provide
state-of-the-art bounds on possible deviations from the PN
predictions [5]}. At the same time, these
theory-agnostic bounds have been used to conduct theory-specific
tests and constrain particular modified theories of gravity (see,
e.g., Refs. [13]}, [14]}, [15]}, [16]}, [17]}).
